Baby Abiy after the TPLF attempted to murder him - his first few days in office - there was an attempted assisination - has been on a mission to cut Tigrays to size.
TPLF were angry when he made peace deal with Oromos militias...without involving them.
After trying to shoot him - he went to Eritrea and made peace...knowing Eritrea hated TPLF.
From there it's been a question of when TPLF and Abiy will go for showdown.
Previous PM was TPLF lackey - and knew when not to cross the line.
TPLF put Abiy to placate Oromos militia - but he wasnt suppose to make any decision.
Why on earth would Ruto hate Luos?
I am not aware of any Kalenjin who hate Luos - Kikuyus and other kabilas who are new in rift valley the relationship is difficult - but btw Kalenjin, Luos, Gusii, Luhyas, and Maasai...the relationship is centuries old. It's like kikuyus and Maasai.
Most kalenjin see Luos as their nilotic brothers who are a little bit cowardly. It doesnt graduate to hatred. The worse it goes is despise. Ruto definitely despise Raila and his Luo elite - because he thinks they dont have what it takes to get power.
Otherwise if they are people who dont fight beyond 2 hours then it's Luo-Kalenjin. Luo-Kalenjin war end swiftly. There is almost no massacres or heavy losses because Luos generally will raise the white flag and Kalenjin will leave them alone.
Ruto will attack Raila because he is main opponent and because gema love it.
Ruto himself - ancestry is Kuria-Gusii - very recent. Some Kalenjin proudly wear their Gusii, ogiek, maasai and luhya ancestry - keeping their old names - and like most nilotic people - knowing their genacological to centuries before
Abiy has a personal vendetta with Tigray. I would say he is quite vengeful given a chance he would exterminate them,I think the war was an excuse for this. Abiy has a very big ego he wants to be emperor of Ethiopia, actually I just heard that his mum had told him he dreamt of him becoming the 7th emperor of Ethiopia.
But Abiy and Ruto are quite similar in some ways. Ruto has a deep seated hatred for Luos,this alone is nothing but given a chance when he is president he won't hesitate to mow them down
